摘　　要：为了研究在磁流变胶抛光中,抛光参数对碳化硅-碳纤维复合材料表面加工质量的影响规律,采用磁流变胶抛光方法,对材料表面进行抛光。研究磁极分布方式、加工间隙和磁极转速对材料表面形貌和表面粗糙度的影响规律。结果表明,磁极分布方式影响待加工表面的磁场分布强度,进而影响表面加工质量。随着加工间隙增大,表面粗糙度下降量先增大后减小,在加工间隙为2 mm处得到最优表面质量。随着磁极转速增大,表面粗糙度下降量先增大后减小,在磁极转速达到800 r/min时得到最优表面质量。In order to investigates the influence of polishing parameters on the surface quality of silicon carbide-carbon fiber composite materials during magnetorheological finishing,a magnetorheological elastomer method was employed for surface polishing.The effects of magnetic pole distribution,machining gap,and magnetic pole rotational speed on surface morphology and roughness were studied.The results show that the magnetic pole arrangement significantly influences the magnetic field distribution on the processed surface,thus affecting the surface quality.An increase in the machining gap leads to an initial rise and subsequent fall in surface roughness reduction,with optimal surface quality achieved at a 2 mm gap.Additionally,an increase in magnetic pole rotational speed initially heightens and then lessens the decrease in surface roughness,with the best surface quality obtained at a speed of 800 r/min.
